General-purpose metal thread sealant

Loctite 572 is an anaerobic pipe thread sealant supplied in a 1.7 fl oz off-white paste tube. It is designed for sealing general-purpose metal threaded connections in maintenance, plumbing and industrial assembly tasks.

Operating temperature range and cure behaviour

The compound remains effective from -65 °F up to 300 °F once cured. As an anaerobic material it cures in the absence of air between metal threads, forming a seal that resists vibration and thermal cycling without shrinking or cracking.

Tube packaging and clean-up

The 1.7 fl oz tube allows direct brush application onto threads, giving control over the amount used on each joint. Excess or misapplied paste can be removed with Loctite solvent, and the product complies with OSHA Hazard Communication Standard 29 CFR 1910.1200.

Questions about this item

How do I apply the Loctite 572 pipe thread sealant from the 1.7 fl oz tube, and what is the common mistake to avoid?

Apply the off-white paste with a brush directly onto clean metal threads. The step people often get wrong is skipping the cleaning; any oil or old sealant left on the threads prevents the anaerobic cure from working properly.

What maintenance or replacement will the Loctite 572 sealant need after the joint is assembled?

Once cured, the dimethacrylate-based sealant is designed to last the life of the connection without maintenance. Replacement is only required if the joint is disassembled, at which point the old material must be cleaned off with Loctite solvent before reapplying fresh paste.

What is the first operating limit the Loctite 572 sealant reaches under sustained high-temperature use?

The maximum operating temperature is 300 degrees F. If the system runs continuously at or above this limit, the sealant will degrade and lose its sealing ability before the minimum temperature of -65 degrees F or any other factor becomes relevant.
